Uniting the all-new No. 0 Intensive Bond Building Hair Treatment with a sized-to-try tube of the world-worshipped No. 3 Hair Perfector, OLAPLEX’s No. 0 Intensive Bond Building Hair Treatment Kit takes hair repair to the next level.

A supercharged addition to the range, the No. 0 Intensive Bond Building Hair Treatment has the highest dose of patented OLAPLEX technology in any take-home product. Intended to work as a two-part process, the restorative No. 0 formula acts as a primer to the No. 3, amplifying the efficacy of both treatments to rebuild hair bonds, strengthen and protect your hair's integrity. As always, the star ingredient is bis-aminopropyl diglycol dimaleate – sounds science-y but it will restore and repair chemical-treated, heat-ridden hair. Working its magic on all hair types and textures – as the whole OLAPLEX line does – this treatment works even if you’ve never tainted your locks with colour or tongs, but it's most beneficial to intensely damaged lengths; the more often No. 0 is used, the healthier your hair will become. We're obsessed!

No. 0 bottle should last 3-6 applications, based on hair length and density.

1. Apply the No.0 to dry hair. Comb the product through to ensure saturation from root to tip.
2. Wait 10 minutes, then apply OLAPLEX No.3 Hair Perfector directly on top of No.0. Comb again to saturate thoroughly, then let the treatment sit for another ten minutes. This treatment is a minimum of 20 minutes, though, just like the No.3 on its own, more significant results occur when keeping it on longer!
3. Once completed, rinse, shampoo, and condition. We recommend the OLAPLEX No. 4 Shampoo and OLAPLEX No.5 Conditioner.
